Kirchoff’s current law (KCL) → Kirchoff’s current law is applicable to junction in a network.
Kirchoff’s current law work on the principle of conservation of electric charge. At any junction in electric circuit the sum of current flowing into the node is equal to the sum of current flowing out of the node, So algebra sum of current in a network is zero. ${\mathit{i}}_1+{\mathit{i}}_2+{\mathit{i}}_5\mathit{–}{\mathit{i}}_3\mathit{–}{\mathit{i}}_4=0$
